-Subject: [PATCH] drm/vc4: Add a getparam ioctl for getting the V3D identity
- regs.
-
-As I extend the driver to support different V3D revisions, userspace
-needs to know what version it's targeting.  This is most easily
-detected using the V3D identity registers.
-
-v2: Make sure V3D is runtime PM on when reading the registers.
-v3: Switch to a 64-bit param value (suggested by Rob Clark in review)
-
-Signed-off-by: Eric Anholt <eric@anholt.net>
-Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> (v2)
-Reviewed-by: Rob Clark <robdclark@gmail.com> (v3, over irc)
-(cherry picked from commit af713795c59fea36161a7debf97dbc10bf652cf7)
-
-v4: Squashed in "drm/vc4: Fix handling of a pm_runtime_get_sync() success case."
